Money left my bank account. Where is my cryptocurrency?

When initiating a bank transfer, you will see the funds pulled from your account immediately upon authorization. This is primarily so the service provider can lock in your quoted price. Due to the irreversible nature of cryptocurrency, the service provider must also ensure that all funds have cleared prior to finalizing the transaction. Depending on your bank, it may take one to two business days for the funds to flow between banks and enter the service provider’s system. Additionally, it may take two to three business days to clear on the service provider’s end. Once your funds have cleared in the service provider’s system, the service provider will transfer your digital currency to your Wallet immediately at the price that the service provider initially locked in. You can see the delivery time of your orders at any time by clicking on the specific order in the email you were sent or inbox message of your Wallet.

When will I receive my cryptocurrency from my card purchase?

Some payment methods such as credit and debit cards may require you to confirm all transactions with your bank. After starting a transaction, you may be sent to your bank's website to authorize the transfer (not applicable to US customers). Funds will not be debited from your bank or credited to your wallet until the authorization process on your bank's site is complete (US customers will see the bank transfer complete immediately with no confirmation through your bank). This process usually only takes a few minutes. If you choose to not authorize the transfer, no funds will be transferred and the transaction will usually expire after about one hour. Note: Only applicable to certain US, EU, AU, and CA customers.

How long does it take to receive cryptocurrency after making a card payment?

Card payments are processed immediately and the crypto is released once all anti-fraud and Know-Your-Customer (KYC) checks have been completed. For first-time transactions, this can take between a few minutes and a few hours, depending on additional verification that may be required. Most subsequent transactions will be processed within about 20 minutes, but occasionally during periods where the service provider is receiving an unusually large amount of orders or when the service provider is running additional checks, it may take longer.

Why was I charged before receiving my cryptocurrency?

As soon as you place an order, the service provider will put a temporary pre-authorization on your card that sets aside the correct amount of funds for your transaction. Unlike an actual transaction, a pre-authorization does not take funds out of your account, it simply puts a hold on those funds until the service provider can confirm you’ve passed the service provider’s verification process, and that your transaction has been sent for processing. Pre-authorizations will show up on your statement as "PENDING" and are not an actual charge.

Why do we use pre-authorizations?

A pre-authorization confirms your payment method is valid, operational, and that there are enough funds to cover the cost of the transaction.

What happens if the transaction gets rejected after a pre-authorization has been placed on my card?

If for some reason your transaction fails or is cancelled, we will cancel the pre-authorization. In many cases, the pending transaction will disappear the same day, but in some instances it can take up to 10 business days. Rest assured, you will never be charged for failed transactions and funds will never leave your account.
